Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

Chatwork

  • Free plan limited to 100 users
  • Free plan message history limited to last 40 days
  • Standard plan pricing: $7/month annual or $8.40/month monthly

Viber

  • Viber has limited relevance outside its strong regions, so building a communication strategy around it in North America or most of Western Europe reaches almost nobody.
  • Ownership by Rakuten ties the app to a commerce and points ecosystem, and account data can be linked to Rakuten services in markets where that integration is active.
  • Business Messages pricing is metered per message, so a company sending high volumes of promotional content can find costs rise quickly compared with a flat fee model.
  • Viber has lost share even in some of its historically strong markets to Telegram and WhatsApp, so its regional dominance is not guaranteed to persist.
  • The desktop client depends on the phone app remaining active and connected, which is a limitation for anyone wanting a fully independent desktop messenger.
